OMG I can imagine what you were feeling when you first saw what had been done to the carpet. GULP
Sounds like Grandma and Grandpa are pretty cool and that's so nice they didn't make you feel bad.

My very first dog I got after moving out on my own was a collie/sheppard mix. I left her in a spare bedroom in the apartment I was renting and came home after work to a whole linoleum floor in little pieces. The room was roughly 11 by 11 feet. Luckily under the linoleum was hardwoos flooring so we refinished the hardwood and it looked better than before with the ugly linoleum. The landlord never said a word and neither did we.

My sons pup is very destructive and has earen some of our hallway drywall, chews and eats everything in sight so we can't let her out of our sight for even a second. She is like a tornado flying through the house looking for something to destroy. Thank God she isn't mine.

Sorry got carried away. Had no intentions of writing all that but my mind and fingers just kept going.

Hope the rest of your visit goes great!
